Here's my latest, just arrived today. The FED 2 changed a lot over its years of production; beyond the obvious cosmetic differences, this very early example, from the first 1000 built, has a few surprises.
The VF focus lever seems to cover a much wider range than it does in the later models, although it is still apparently the same excellent VF/RF as all FED2's. The focus cam follower is not the usual quarter circle sector, but the sharp point seen in very early FEDs and Leningrad cameras. The RF window is not just cosmetically different, but has a completely different mechanism for vertical alignment from that of later FEDs, which use a rotating collar like the Barnacks. The lens has a funny design of infinity catch, necessitated by the very thin lens mount flange.
It seems to be great mechanically as well as really nice cosmetically, and it looks like I need to burn some film.
Cheers,
Dez
